Explanation:

Given:
- Total number of marbles in the jar = 18
- Probability of drawing a red marble = 2/3

Finding the number of yellow marbles:
- Let the number of yellow marbles be y
- Since the probability of drawing a red marble is 2/3, the probability of drawing a yellow marble would be 1/3
- The total probability of drawing either a red or a yellow marble is 1

Calculating the probability of drawing a yellow marble:
- Probability of drawing a red marble = Number of red marbles / Total number of marbles
- 2/3 = 18 / (18 + y)
- Solving the above equation, we get y = 6

Therefore, the number of yellow marbles in the jar is 6.
